A surprise awaits the competitors at the start of the episode as they choose their opponents to compete in the “Progressive Drive Challenge” and battle for immunity. The competitors receiving immunity will enjoy an afternoon off and take a tour of 'The Bunker,' the former top-secret U.S. Government relocation facility for Congress and an emergency Cold War fallout shelter, located at The Greenbrier. Meanwhile, on the golf course, the other players fighting to stave off elimination receive a twist that threatens to eliminate one of the season’s most colorful characters.
